To all whom itfmay concern. 1

Be it known that 1, Louis B. PRAHAR, a, citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State. of New York, have invented a newandusefu'l Improvement in Locks for B'ag-Frames'," of which thefollowing is a full, clear, and exact description. v This invention relates to certain improvements in looks especially adapted for use on the frames of bags, urses, and like articles, and more particular y to that type of lockin which there is em loyed a casing secured to one jaw of the engage with otherjaw. j The special object of the invention is to provide a lock in-which the thumb iece of the latch is formed integral with the ody of the latch and extends through an 0 ening in the side of the casin and in which t e casing is so formed that t e thumb piece may be readily moved to a osition parallel to the bag frame, but inwiiich further movement is prevented by engagement of the thumb piece with the casing.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts mall the figures. i 1

Figure 1 is a erspective view of a frame viewed from be ow, and the improvedlock e elevation of the lock drawn upon an enlarged scale,-and a portion of the jaw of-the bag frame to which the lock is applied; Fig. 3 is a transverse section taken practically on the line 3--3 of Fig. .2, showing the two jaws of the frame closed and held closed by the improved lock; and Fig. 4 is a detail perspective view of the latch member of the lock.

My improved lock is adapted to besecured to any suitable form of ba frame, as, for instance, one having hin e jaws A and A The lock may be secure to either jaw and is of such width thatit'extends across the other jaw. As illustrated, the lock is secured to the jaw A and includes a casing B and a catch 0. The casing is formed from a single piece of sheet metal, and is stamped to form a body and outwardly-extending base flanges, the latter serving tofacilitate the attachment ag frame, and having;f mounted therein a latch member adapted to projections or offsets upon the i l der 14 fora applied thereto; Fig.2 is a sectional inner. s1

Yof the casing tothe frame jaw by rivets 10.

a The body of the casing comprises two su erimposed portions 17 and 18, the former aving the flan es above referred to, and being of a -.width slightly less than the width of the two jaws of the frame. The latter body ortion 18 is somewhat shorter than the b0 y portion 17, and-is also somewhat narrower, the "difference in'width at each sidebeing a proximately equal to the'thickness of t e metal of which the casing is formed. The

casing presents a shoulder 14, extending en- .tirely around the same and formed by the intersection of the two body portions of differentsizes. The lower body portion 17 is provided with an opening 15 in the side thereof and extending up to and including the shoulportion of the length of the casing. w a I Within. the casing I rovide the latch shown'inperspective in ig. 4. The latch includes a curved body member 11, of a width substantially equal to the width of the interior of the body portion 17 and having a thumb piece 12 extending upwardly from the central portion thereof at an obtuse angle. The curvedbody member of the latch is of a length slightly greater than the length of the body portion 18, so that the upturned ends of the latch engage with the shoulder 14 at the; ends of the casing. The thumb piece 12, at the base thereof, that is, at the point of attachment with the body member 11, is of a length substantially equal to the length of the opening 15, but the outer end of the thumb piece is of a length greater than the length of said opening. The body member 11 of the latch is provided with one or more openings13, adjacent the base of the thumb piece, and the jaw A is provided with a correspondingnumber of pro ections or 0&- sets 16, adapted to be received within said openings 13.

In the operation of my improved lock, the

. parts occupy the positions indicated in Figs.

2 and 3 when the jaws are in engagement witheach other. The central portion of the curved body member lies in engagement with the outer surface of. the two jaws A and A .and the thumb piece 12 extends through the opening 15 at an angle to the plane of said jaws. In order to separate the jaws, the thumb piece 12 is pressed toward the casing until it occupies the position indicated in dotted linesin Fig. 3. The thumb piece cannot bend in respect to the latch body, as the upper end of the opening 15 is shorter than the portion of the latch adjacent thereto. The only possible movement of the latch is an upward movement of the central portion to bring the openings 13 away from the projections or offsets 16. As the base or lower edge of the thumb piece reaches the upper end of the opening, the thumb piece may move to a position in alinement with the side of the body portion 17, and closely adjacent to and parallel with the side of the body portion 18. This engagement with the side of the body portion 18 prevents further move ment of the latch and also prevents bending of the thumb piece in respect to the latch boc y.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

The combination with the jaws of a bag frame, of a lock consisting of a box or casing formed of two portions, one portion adapted to be secured to one jaw of the frame and the other portion of less width and less length than the first-mentioned portion and extending outwardly therefrom, said first-mentioned portion having an opening in the side thereof extending from the lower edge of said casing to the lower edge of the second-mentioned portion, a latch formed of spring metal and comprising a body section extending longitudinally of the first-mentioned. portion of the box or casing and having its ends held against outward movement by the inner sur face of the outer side of said first-mentioned portion and having the central portion there of in engagement with the jaw carrying said casing, and a thumb piece integral with said body portion and extending through said opening and disposed at an obtuse angle to said body portion, the thumb piece being movable within said opening to a position substantially in the plane of the side of the first-mentioned body portion of the casing, engaging the side of the second-inentioned body portion of the casing, to bring the central portion of the latch out of engagement with the bag frame, and coaeting means for preventing separation of said jaws when the central portion of said latch is in engagement therewith.

In testimony whereof I have signed. my name to this specification in the presence ol two subscribing witnesses.
